On the other hand, the second pulley 80d attached via a shackle or the like is wound from above. Then, the wire 80b wound around the second pulley 80d is attached to the wire attachment portion 80e at the upper end of the pole 80.

  Thereafter, by winding the wire 80b with the manual winch 80c, the goal post 10A and the extension goal post 50A are pulled by the wire 80b, and the hinge structure of the fixed support portion 30A is used as a fulcrum as shown in FIGS. It gradually turns in the direction of arrow D shown in FIG. Then, with the goal post 10A and the extension goal post 50A held in the upright position, bolts 30u are respectively inserted into the through holes 30l of the first plate 30b and the through holes 30q of the second plate 30c of the fixed support portion 30A. The first plate 30b and the second plate 30c are fixed to each other by being inserted and screwed together. Next, the goal post 10B and the extension goal post 50B are brought into an upright state by the same method as described above.

  The connecting members 40A and 40B are preferably attached in advance to the extension goal posts 50A and 50B (or the first tubular member 10a of the goal posts 10A and 10B). Then, a stepladder is installed at each of the left and right installation positions 3, and the crossbar 20 is transported to the positions of the connecting members 40A and 40B by a plurality of people. It connects with each of goal post 10A, 10B).

  After the assembly work is completed, the pole 80 is removed so as not to hinder the game. In addition, a resilient mat or the like is wrapped around the lower part of the extension goal posts 50A and 50B (goal posts 10A and 10B in the case of a goal 1 having a height of 13 m) so that the player can extend the goal post 50A during the game. , 50B (goal posts 10A, 10B) should be injured even if it hits.

  As described above, according to the athletic goal 1 of the present invention, the extension goal posts 50A, 50B are detachably connected between the lower ends of the goal posts 10A, 10B and the fixed support portions 30A, 30B.
